As you can see, when the
number submenu's and item's begins to grow the html begins to look a little
cumbersome. For this reason we have built in the ability for the menu bar to
retrieve the menu and item data from text files. In this way the menu and item
data is far easier to manage and the html will look cleaner. In this example
we place all the menu data in a file called menudata.txt and all the item data
in a file called itemdata.txt.
